Geological Survey objects to a forecast saying there's a 99.9% chance of a significant earthquake in the Los Angeles area by 2018.
The Online Tornado FAQ (by Roger Edwards, SPC)Background photo courtesy NSSL. On 2. 4 May 2. 01. FAQ witnessed and photographed a merger of a long- lived, violent tornado with a satellite tornado that had grown about as large and strong, based on mobile Doppler- radar data. Theodore Fujita developed.
Fujita 1. 97. 1, Fujita and Pearson 1. The original F- scale should not be used anymore, because it has been replaced by an enhanced version. Different winds may be needed to cause the same damage depending on how well- built a structure is, wind direction, wind duration. The newer EF- Scale wind groupings were rooted in engineering study of wind effects, with the 3- second gust thresholds rounded to the nearest values that are divisible by 5. For the original F- Scale, Fujita plotted hypothetical winds higher than F5; but as mentioned in the previous answer above, they were only guesses.
There is a statistical trend (as documented by NSSL's Harold Brooks) toward wide tornadoes having higher damage ratings. The main problem with deploying anything packing enough energy to realistically stand a chance at affecting a tornado (e. BACK UP TO THE TOP. Nobody knows, for certain. Miller's recollections of the event; and they.

- Roger Edwards of the Storm Prediction Center presents basic Frequently Asked Questions and the answers about tornadoes.
Most of the damage from a tornado happens one of two direct ways: exposure to extreme wind or impact by flying debris. Another reason is that hazardous materials may have been released by the tornado- -such as natural gas, medical waste, gasoline, other dangerous chemicals, or sewage. Some oddities (like that chicken example) defy ready explanation, without direct evidence such as video from a security camera. The most. widely used method worldwide, for over three decades, was the F- scale developed by Dr. S., and probably elsewhere within a few years, the new Enhanced F- scale is becoming the standard for assessing tornado damage. In Britain. there is a scale similar to the original F- scale but with more divisions; for more info, go to. TORRO scale website.
How does seeing a bunch of busted trees and houses help with understanding tornadoes? The benefits of this extend into many areas, including: improving building codes for resistance against most tornadoes (since most tornadoes are weak anyway), the insurance and re- insurance industries, construction designs and practices, and comparisons of tornado damage with their weather situations and radar signatures (for improved watches and warnings). That depends on where you are. Opening the windows is absolutely useless, a waste of precious time, and can be very dangerous.
NIST has recommended raising standards nationwide, based on their study of the Joplin tornado from 2. BACK UP TO THE TOP. Community tornado shelters are excellent ideas for apartment complexes. Worth in 1. 99. 5.
Worth Metroplex, especially during rush hour gridlock (with up to 6. Oklahoma. Worth has compiled a very detailed study of several such violent tornado disaster scenarios in the Metroplex, which could be adapted to other major metro areas as well. This idea has some merit. Tornado reports have increased, especially around the installation of the NEXRAD Doppler radar system in the mid 1.
Such. report totals are in an. SPC. On average, tornadoes kill about 6.
It's rare; but we don't know how rare, because an outbreak like that arguably has only happened once since any tornado records have been kept. Finley, in the 1.
U. Hundreds of storm chasing videos and several TV documentaries have been made, most since the mid- 1. They typically have little or no mention of safety, forecasting skill, learning, extensive . If it is a. low- hanging cloud with no rotation, it is not a funnel cloud. There are important distinctions between satellite and.
This paper (PDF) offers more documentation and examples of satellite tornadoes. For more in- depth histories, please see this formal article by Chuck Doswell and an informal converence paper by Howie Bluestein. VORTEX- SE will also determine the best methods for communicating forecast uncertainty of these events to the public, and evaluate public response.
